obtain IP addresses on the corresponding network and other network parameters from the Firewall. You
can use the display dhcp server ip-in-use command on the DHCP server to view the IP addresses
assigned to the clients.
Self-defined option configuration example
Network requirements
As shown in Figure 104, the DHCP client (the router) obtains its IP address and PXE server addresses from
the DHCP server (Firewall). The IP address belongs to subnet 10.1.1.0/24. The PXE server addresses are
1.2.3.4 and 2.2.2.2.
The DHCP server assigns PXE server addresses to DHCP clients through Option 43, a self-defined option.
The format of Option 43 and that of the PXE server address sub-option are shown in Fi
gure 83
and Figure 85, respectively. The value of Option 43 configured on the DHCP server in this example is
80 0
B 00 00 02 01 02 03 04 02 02 02 02. The number 80 is the value of the sub-option type. The
number 0B is the value of the sub-option length. The numbers 00 00 are the value of the PXE server type.
The number 02 indicates the number of servers. The numbers 01 02 03 04 02 02 02 02 indicate that the
PXE server addresses are 1.2.3.4 and 2.2.2.2.
